Workshop and Butler Farms Tour: September 18, 2008

Sampson County Agri-Exposition Center
414 Warsaw Road
Clinton, North Carolina 28328

Increasing desire for renewable energy and greater environmental protection, and the growth of the livestock industry, have created the atmosphere for the viability and growth of anaerobic digester systems in the Northwest. Management of odors, water quality, air emissions, and nutrients are major issues facing dairy farmers and the citizens in the region. However, anaerobic digester systems have proven to be one solution to many of these issues, as well as a viable energy source. These technologies not only address many of the environmental concerns surrounding manure management, but also create opportunities for revenue from energy generation, nutrient value, fiber recovery, and carbon credits.

This free workshop, hosted by Environmental Credit Corporation (through a U.S. Department of Agriculture grant), EPA Region 4, and AgSTAR, provided a broad overview of anaerobic digestion of swine manure and other related issues. The presentations are posted below.
